There are certain spans of DNA that have higher than usual concentrations of certain nucleotides. One particular range has higher than expected C's and G's and specifically has the following proportions for A, C, G, and T, respectively: 0.2, 0.3, 0.3, 0.2. Researchers have a span of DNA and it is not known whether or not it comes from this region of higher than expected C's and G's. Test whether the given proportions are a good fit for the data here. The counts of the different nucleotides from this strand are as follows: Data A C G T Count 74 75 77 74 Find the test statistic for this test. Note: Round to the nearest thousandth if necessary
